Lee Swanson's Ultimate Probiotic Formula is a highly potent probiotic supplement, featuring 66 billion organisms per veggie cap. It includes more than 20 billion acidophilus organisms along with select cultures like the famous Kyo-Dophilus blend. But that's not all. Ultimate Probiotic Formula also includes 100 mg of prebiotic NutraFlora short chain FOS to nourish the probiotic organisms and help them thrive. Be sure to take the supplement with food as directed on the label. Doing so will raise the pH level of your stomach to a 3 or 4, which effectively allows the organisms to survive the acid in your stomach and eliminates the need for an enteric-coating.

Rated 5 out of 5 by Eggers A good product
I take one capsule daily and I also open up a capsule and pour the powder in to my home made kefir and yogurt to give an extra probiotic boost. I also stir an opened capsule into cottage cheese too.

Rated 4 out of 5 by xXxaexXx Seems promising
After having an independent laboratory confirm the contents of the supplement I soon discovered that these were a good buy for the money.

I bought these thinking they would be great due to potency, but was VERY disapointed. I had been using Dr. Stephen Langer's Ultimate 16 Strain Probiotic and was really happy, but decided to try swanson signature.. They do nto work at all. Dr. Stephen Langer's Ultimate 16 Strain Probiotic is 100 times better..

Rated 5 out of 5 by youandme2 great item
I've bought this item for years because it has everything and more that I wanted in a probiotic. I am on a fixed income so I have to wait until it is on a special so I can stock up on it. Prices have gone up on so many of my favorites that I even tried to find similar items but none matched the above item. I used to work in the health food and vitamin field many years ago.

Rated 5 out of 5 by TakeYourVitamins Love it
I've tried other probiotics that were a little cheaper, but for me, this one works the best. I recommended to my mom and now she's hooked too.

Rated 5 out of 5 by d7Fm39Vc Love this probiotic
I have tried many probiotics. Most were a lot more expensive. At the present time, I am trying a different Swanson probiotic, but I will be returning to this one. This is the best one of all! My granddaughter(a college student) refuses to take any other probiotic. I order it for her so she won't run out of it. I love all Swanson products and I use many of them, but for me, this Lee Swanson Signaure Line of probiotics is a necessity. Does wonders for the colon!

Rated 5 out of 5 by Calvinsman Best of the class
I like several of the probiotic formulas offered via Swanson's label. All of them make a positive difference. This one seems to keep me in best shape. The total bacteria count per price is also excellent.

Rated 5 out of 5 by AthenaAlso Effective and convenient
I've found this Swanson's product to be effective where others have failed and I esp like the convenience of taking it just once daily.

Rated 1 out of 5 by oldredneck Ultimate Probiotic Formula
In my opinion, this product is a total waste of my money. It didn't do the job it was supposed to do, but just the opposite. I will no longer be ordering any products from Swanson. Combined with products not doing the job, to really old dates of manufacture, to long delivery times, and even more negative things, I've finally decided not to waste my money buying from this company.

Rated 5 out of 5 by Jazzy2 Great Product
I bought these for my husband that has problems with his digestive system. He has never found anything that works as well as these do. They deliver on what they say they do. We are sold for life!

Rated 5 out of 5 by Favorite super
I have used this product for quite awhile and I find it very effective and convenient. I especially like the fact that it doesn't need to be refrigerated, that makes it much easier when I travel. I also prefer using Swanson Brands whenever possible and this product is well worth the price.
Try it, it will prove itself!!!

Rated 5 out of 5 by coleen Highly recommended!
I have tried many probiotics over the years and I saw more positive changes with this product than any of the others, regardless of price. I only ordered one bottle to try it, but am now ordering the 3 packs for better value. Highly recommended!

Rated 5 out of 5 by Winnmusic Probiotics a must!
Perhaps one of the best probiotics on the market to date and very affordable - at 66 billion you can't go wrong

This isn't a bad probiotic, it just didn't work as well for me as the PB8.

Rated 5 out of 5 by BOBL Works for me.

I've been using the product for about a year and will continue to use it.
